PORTABLE CYLINDRICAL DRIER FOR FABRICS.

SPECIFICATION forming part of Letters Patent No. 487,600, dated December6, 1892.

Application filed April 15, 1892.

To all whom it may concern.-

Be itknown that I, ALBERT BOROHARD'I, of Brooklyn,New York, haveinvented a certain Improvement in Portable Cylindrical Driers forCurtains and Fabrics of Delicate Texture, of which the following is aspecification.

The object of this invention is to facilitate the drying of curtains andfabrics of delicate texture, which require to be symmetrically stretchedin order to retain their shape in drying.

The invention consists of a hollow cylinder of muslin or other suitablefabric having its end portions circumferentially inclosing and fastenedto two light wheels loosely mounted upon a shaft provided withadjustable means for holding apart said wheels, and thereby'stretchingsaid muslin cylinder longitudinally.

The muslin cylinder is preferably marked with parallel circumferentiallines to serve as guides to facilitate the symmetrical adjustment andfastening to the cylinder of the objects to be dried.

The accompanying drawings, illustrating the invention, are as follows:

Figure 1 is an end elevation. 7 side elevation,partly in section. Fig. 3is an isometrical perspective of the collapsed cylinder. Fig. 4, is anelevation of the shaft detached. Fig. 5 is a longitudinal sectional viewof a portion of the cylinder, showing one of the hoops in transversesection and showing the outerportion of one of the spokes.

The portable drying-cylinder illustrated in the drawings is composed ofthe tube or cylinder a, of muslin or other suitable fabric, the endportions 0. and a of which are respectively turned inward and fastenedto the outer edges of the hoops b and cin any convenient manner-as, forexamplaby means of a series of tacks d, driven through the overlyingtapes I) and 0 into the hoops. The hoop b is provided with spokes,preferably consisting of two crossed strips of wood e and f, havingtheir ends fastened to the inner edges of the hoops, and the hoop c issimilarly provided with spokes consisting of the crossed strips of woode and f. At the places where the strips cross they are provided,respectively, with the perforations e and f for admitting the shaft g,which constitutes the axis of the Fig. 2 1s a Serial No. 429,316. (Nomodel.)

cylinder. The shaft 9 is provided with several transverse perforations hto receive the pins h and 71. by means of which the hoops are held atsuch distance apart as will properly stretch the muslin cylinder a.

The muslin cylinder is provided with the system 1: of parallelcircumferential marks, which serve as guides to indicate the appropriateposition upon the cylinder for the object to be dried. For example, themarks facilitate the pinning to the cylinder of a currain with its edgesparallel to eachother, whereby the conditions of parallelism will bemaintained during the drying of the curtain. It will of course beperceived that the cylinder may be of any desired dimensions. For dryingcurtains a cylinder, say, of four feet in diameter and five feet inlength will usually be suitable.

The entire structure is Very light and when required for use may besupported by resting the projecting ends g g of the shaft upon the backsof two suitably-placed chairs or other objects. turned step by step byhand as the curtain or other object to be dried is being pinned to itsperimeter. When desired,the transverse pins h k can be withdrawn, andthe shaft g, being removed, the hoops b and 0 can be pressed togetherand the cylinder collapsed, as illustrated in Fig. 3. In this collapsedcondition the structure occupies very little space and can be readilystored away until again required for use.

Each of the hoops, with their cross-pieces, constitutes alight wheel ofsimple construction. The flat cross-strips which serve as spokes areadapted to spring in the direction of the axis of the cylinder, andhence impose an elastic stretching strain upon the muslin perimeter ofthe cylinder when the wheels are forced apart by the insertion of thepins h it through the appropriate transverse holes h on the shaft g.

Ample room is afforded by the spaces between the spokes for access tothe interior of the cylinder for the purpose of appropriately insertingthe pins. It will therefore be seen that the shaft g, transverselyperforated, as shown, and provided with the removable pins h h*,constitutes a stretcher for more or less In this position the cylindercan be tightly stretching the muslinperimeter of the cylinder in thedirection of the axis thereof.

What is claimed as the invention is- 1. In a portable drying-cylinder,the combination of two light wheels and a hollow cylinder of muslinhaving its end portions circumferentially inclosing and fastened to saidwheels, respectively, with a stretcher for bold ing said wheels apart,and thereby stretching said muslin cylinder longitudinally.

2. A hollow cylinder-of muslin with itsend portions circumferentiallyfastened to the perimeter of two light wheelsloosely mounted upon acentral shaft provided with removable transverse pins for holding saidwheels apart.

3. A hollow cylinder of muslin with its end portions circumferentiallyfastened ,toithet perimeter of two light wheels provided with spokesadapted to spring in thedirection of.

E holding said hoops at: prescribed distances the axis of said cylinder,in combination; with a central shaftyprovided-with adjustable means forv holding said wheelseapart, and

thereby imposing anelastic outward strain upon theopposite ends,respectively, of said, muslin cylinder.

4:. The combination, as herein set forth, of the muslincylinder a, thehoop 1b, the crosspieces 6 and f, the hoop c, the cross-pieces e and f,the shaft 9, of greater length than the cylinder a, and the transversepins h and b 5. A tube of muslin, two hoops inserted within the-oppositeends-thereof, respectively, and fastened to the muslin by having tackedto their outer edges the inwardly-turned end portions of said tube,aincombination with two systems of crossed slats'having their endsfastened, respectively, to the inner edges of the hoops, a centralshaft. inserted through perforations in' the crossed portions of saidslats; suitably-located transverse holes in said shaft, and two pinsadapted for insertion in said transverseholestor thepurposeof bearing,respectively upon- ;the;inncr surfaces of said systems-.oftcrossed slatsand thereby aparh- ALBERT .BOROI-IARDT.v Witnesses:
